Detailed Description

Brief introduction  Only two times calibration a year and doing measurment immediately just after turn on the meter.  High precision that can reach 0.1ug/l.  Zero calibration does not needed at most time .  Lower consumption of the electrolyte that it can be used at least 6 months after once fufill.  The design of the flowing sample system guarantees the measuring signal should be more stable.  It can collect the data automatically according to the presetting interval time during measuring.  It can store the measuring place, time, date and the concentration value as its high memory capacity.  It can output the data with computer or printer .  It can detecct the voltage of the battery and shut down automatically .  Background light can be used in the dark environment.  You can equiry the record of the measuring data and calibration data that stored in the instrument.  It can be last for 15 hours with the rechargeable battery.( 2×3.6V)  It has the recharging indicating and full charge indicating on the recharger base.
